SPECIFICATION forming part of Letters Patent No. 305,835, datedSeptember 30, 1884.

Application filed October 30, M7383. (No model.)

To all whom it may concer/z.:

Be it known that I, JOHN R. MORGAN, of Alliance, in the county of Starkand State of Ohio, have invented certain new anduseful Improvements inAccumulators; and I do hereby declare the following to bea full, clear,and exact description of the invention, such as .will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in hydraulic accumulators, theobject being to provide an accumulator of such construction that thepressure may be readily and easily l varied for the `difference kinds ofwork re,-

quiring varying pressures; and with this end 1n View my inventionconsists in certain featuresof construction and combinations otparts, aswill be hereinafter described, and pointedy out in the claims.

In the accompanying drawings, 'Figurel a View in side elevation of myimproved accumulator. Fig. 2 is a view partly ,in side elevation andpartly in vertical section of the same. Fig. 3 is a transverse section.Fig. 4 is a transverse section of the main hydraulic cylinder and itsplungers. Fig. 5 is a plan View of the locking-ring, and Fig. 6 is aplan view oi' one of thelocking-bars.

A represents the base-plate, upon which stands and is bolted the base a.of the main hydraulic cylinder B, which is provided at its upper endwith a bearing, l), and a stuffing-l boX, b.

Vithin the cylinder B islocated the rain or plunger C, which snuglyr tsthe bearing b ci' the cylinder B, and is provided at its upper end witha stuffing-box, c,- and at its lower end with an opening, c', equal tohalf its diameter. The ram or plunger C is also furnished vnear itsupper end with abearing, d, within which snugly tits the ram orplungerD, which is provided at its upper end with a stuffing-box,

c bearin j' and at its lower end with an o ien-4 i i l ing, e", equal tohalf its diameter. y

Within the ram or plunger D is located the v small ram. or plunger E,which fits within the bearingf of the plunger D. The upper end ofthe ramE isconstructed with a shoulder, gand an extension, g', which fits in acorresponding recess or cavity, (ji, in the diskbracket F, a suitableleather packing, h, be-

ing interposed between the upper end of the rain E andV the cavity inthe disk-bracket, whereby a tight joint is insured between such parts.top of the disk-bracket through to the cavity formed therein, andcommunicates with the small openingor borej,which extends throughout theentire length of the ram E. A safetyvalve, K, is located over the upperend of the bore i in the disk-bracket E By this construction the entirepressure of the accumulator may be allowed to pass throughy the ram' Eto the safety-valve K, which latter is automatic in its movements, andrelieves the presspump or engine should fail when the accumulator isfilled. The water escaping from the safety-valve'when an undue pressureis exerted in the accumulator may be the accumulator-cylinder or pump,suitable valves being employed for that purpose.

As'the `construction andv arrangement of valves for effecting the sameresult in other types ci' hy claim is made thereto in this application,it is not deemednecessary to illustrate or give a detailed descriptionof such parts.

From the 'bracket-disk F is suspended the -lar t-ank formed of lightsheet metal, with a central opening, l', of sufiicient diameter toenable the tank t0 encircle the main cylinder B. This tank is providedwith east-iron frames secured, respectively, to its upper and lowerends, which are'bolted or riveted to the body of the tank. y Thetopframe has openings, as

metal scrap, J, of such quantity as will insure the desired weight. Thebottom .of the tank is provided with a layer of sand or small gravel,k', which. serves as a cushion to the metal scrap should the tank fallbyreason oi' any accident or breakage of any part. ed from Athe diskbracket F byrneans of the suspension-bolts cast-,iron frames J, and aresecured at their lower ends by means of nuts Z. Suitabledistance-pieces, I, encircle-the suspension-bolts or 4bars'H between thedisk bracket F and the A small opening, i, extends `from the4 wasted,orby. return-pipes be conveyed to the lower end of main load G,\vhichlatter consists of an annushown in Fig.' 8, through which is insertedTank G is suspend.

Both the upper and` ure in the event that thegear forstoppingthe draulic apparatus is old-and no Il, which passthrough the lower yframes J Jare provided with` perforated lugs m,which?encircle the fguiideqiods D L, the lower ends of which are rmlysecured in the lugs n n on the base-plate, and at their upper endssecured in any desired manner to the roof or to bearings attached totheside Wallsl of the building.

EAgain, it is not`necthe lower end of the cylinder B, which has the" effect of raisingthe three rarnsor plungers C D Euand the weight G. The internal pressurefrom the pump, acting on all surfaces, retainsf7o the plungers againstany lateral movement or displacement, andalso prevents the rams fromtelescoping. When' the valve is opened to conduct Water, under pressure,through pipeN G and all the plungers will descend, thereby subjectingthe column in the cylinder B to the -maximum area of the plungers orrams, which will produce the minimum pressure-namely,

8o To secure a pressure of seven hundred and seventy-seven pounds to:thesquare inch, the

ram `or plunger C is. lockedagainst vertical j:=mov.ement, Whichiseffected by rotatingthe :steel ring Q-on saidvramasufcient .distance @tocause the locking lugs or flanges t on` the ring lto Aengage theshoulders r on the lockingbars P. `The pump -isthenoperated andavaiterlforced into the-llower endiof; the cylinder AfB, causing the. plungers-Dand -IE to: ascend r andv raisethewveightl G,f.and in; their descent'thecolumn ofwater in-.the cylinderiB willbe --subjected to a pressureequalito the maximum varea of thetwo plungers DE, thereby insuring? theincreased pressure, as specilied.`

"To insure a lpressure.iofnifteen 'hundred f pounds per square inch, theplungers Cfand D "larel-o'cked to the steel' barsP by the lockingy ringsQ, as hereinbefore,described,A soc that when the pump is putinto-operation the. ram Ico vor plunger E and.

Iltzwill `be observed. that. in .adjustingathe machine for its varying@pressures the load'or the varying pressures is effected ina' ready4mannerandffat a .slight outlay of time-'and power. Should any of theplungers Yor cylinessary to disturb Aor block up the weight -G to vpackthe stufng-boXes,as they areialllocated Eat the upper ends oftheplungers, and arefreadily accessible for repacking when desired.

',While Iwhave sh'ovvnand described an accumulator providedl with threelrams or plungers 'forsecu-ring three different pressures, Idofnot limitvmyself to this number, because theaccu- .-mu1atorinay be providedfwithany number of 13o rams =or plungers, and thus insure any'desired .Widerange of work. Again, the WeightYG','in

parts might be devised without involving a` departure from my invention,Iwould have it understood that I do not limit myself to the exactconstructionand arrangement of parts shown and described; but,

Having fully described my invention, what l claim as new, and desire tosecure by Letters l. In an accumulator, the combinatiomwith a cylinder,two or more rams or plungers located within the cylinder, a disk-bracketor cross-bar secured to the upper end of one of the plungers, and aweight encircling the cylinder, suspended from the disk-bracket, ofmeans for detachably connecting one or more of the other rams orplungers with the weight,

3o substantially as set forth.

2. Inan aecumulator,the combinatiomwith a cylinder, two or more rains orplungers located within the cylinder, a disk-bracket or cross-barsecured to the upper end of one of the pluugers, and a weight encirclingthe cylinder and suspended from the cross-bar' or disk-bracket, ofshouldered locking-bars secured to the cylinder, and locking-ringssupported in the annular shoulders of the rams, and provided with lugsor flanges and handles, substantially as set forth.

3. In an accumulator, the combination, with a cylinder, of two or morerams located Within the cylinder, one ram being arranged to move withinanother, the inner ram being provided with a bore extendinglongitudinally throughout its length, and a safety-valve communieatingwith` said bore, substantially as andi'or the purpose set forth.

4. In an accumulator, the combination, with a cylinder and rams orplungers, of an annular weight, G, provided with end frame, J, havingperforated lugs m, and theguide-rods L, substantially as and for thepurpose set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
